To all whom 2'25 may concern.-

e it known that I, HYMAN B. RUBIN, a citizen of the United States, andaresident of the city of New York, borough of the Bronx, in the countyof Bionic and State of New York, have invented a new and ImprovedlVlultiple-Mitering Attachment, of which the following is a full, clear,and exact description.

This invention relates to attachments for mitering machines and has foran object to provide an improved construction wherein a multiple numberof printers rules may be mitered at the same time.

Another object of the invention is toprovide an attachment for miteringmachines whereina plurality of rules may be mitered at the desired anglesimultaneously or cut off square as preferred. I I

A still further object of the invention is to provide an attachment formitering machines which maybe readily applied and removed and adjustedfor different lengths of rules, the attachment being capable ofreceiving one or a' large number of rules at one time. 1

In the accompanying drawing s- Figure 1 is atop plan view of a miteringmachine of a' conventional type, showing an attachment embodying theinvention applied thereto.

Figure 2 is a fragmentary view of the machine shown in Figure 1 anddisclosing a modified structure of attachment.

Figure 3 is a fragmentary top plan view of the machine shown in Figure 1with a further modified form of the invention shown applied thereto.

are identical except that one is provided withrev'erse angles to theother as indicated particularly in Figures 5 and 6. The fitting 15 isslidingly fitted on the angle bar 13 by the dove-tailstruc'ture asindicated in Figure l and is locked against movement by a suitable thumbscrew 17. This attachment is provided with parallel angle surfaces 18and 19, the surface 18 being overlapped by a projection or lug 20 whichextends at a 9&5 angle from the surface 18. Preferably, there ar'eprovided apertures 21 and 22 in the attacliinent'15 extending inwardlyfrom the surfaces 18 and 19 whereby any suitable form of lug or block 23may be used for varying the angleof the} surfaces 18 and 19.

As shown injFigure 7 thefiller block 23 is arranged with a pin 24fitting snugly into the aperture 21, saidblock being formed to changethe effective angle to a right angle to theangle bar 13 so that therulesmaybe cut ofi square as indicated in Figure 2. In some instances itmight be desirable to miter the rules ata different angle from a 15angle and when this is the case a filler block 25 may be provided toproduce the desired angle of face superimposed on face 18, said fillerblock 25 having an overhanging lug 26 whereby it is supported in placetemporarily while the rules are being mitered. The overhanging lug 26 isdesirable because the blocks 25 are comparatively thin and would notreadily support a pin 24. though when the blocks are thicker as shown inFigure 7 the pin is a preferable structure.

In operation, the attachments 15 and 16 may be slid into position on theangle bars 13 and 14 or may be slid therefrom as desired.

against the bar 14 and fitting against the face 18 of attachment 16. Thecutter of the mitering tool 11 is then operated for securing the miterdesired. The rules are then moved over to a position against the bar 13as shown in Figure 1 and the mitered ends When it is desired to miterrules of a certain length, one or more are arranged of the rules aremoved into engagement with the surface 18 of attachment 15. This willproduce a stepped formation as clearly indicated in Figure 1. l/Vhen therules are thus properly arranged, the mitering instrument 11 is operatedfor securing the proper miter at the opposite end of the respectiverules. In this Way a large number of rules may be mitered at the sametime and all the miters will b exactly alike as well as all of the ruleswill be exactly the same length. In case a group of rules is desired toform a frame or other purposes and the rules of the said group are ofdifferent lengths, the arrangement shown in Figure 3 is used, which.

is merely the transposing of the attachments so that the attachment 16will be on th bar 13 and attachment 15 on bar 14.

Very often a combination border made up of two or more different rulefaces is required and it is necessary that the miters be as perfect asis possible. WVhen this is the case the group of rules is arrangedagainst the bar 14: and one end mitered with the straight end fittingagainst the surface 19 of attachment 15. The rules are then reversed andarranged as shown in Figure 3 with the mitered ends fitting against thesurface 19 of attachment 16 and the opposite ends mitered. Thisarrangement will provide as accurate a miter as though only singlepieces of rule were mitered. It will be evident that the attachment maybe used to miter a single rule but the desirable feature is theconstruction which will permit a number to be mitered at the same time.

In providing rules under the old method, each piece is miteredindependently while according to the present invention several pieces ofthe same length can be mitered in one operation.

What I claim is 1. An attachment for mitering machines,

comprising a body having parallel faces, said faces being arranged at anangle to the rule engaging the bar of the mitering machine and extendingto a point in contact with said bar.

2. An attachment for mitering machines, comprising a body adapted to beremovably mounted on the bar of a mitering machine, said body having apair of parallel faces arranged at angles from said bar, and aprojection overhanging one of said faces, said projection being parallelwith said bar.

3. An attachment for mitering machines, comprising a body provided withparallel faces, an overhanging shoulder overhanging one of said faces,and a filler block removably connected with the body and adapted to fitagainst either of said faces for presenting a different angle.

4. An attachment for mitering machines, comprising a body adapted to beremovably clamped to one of the bars of the rule holder of a miteringmachine, said body having a rule engaging fac arranged at a 45 an gle tosaid bar, and an overlapping projection overlapping said face andextending substantially parallel to said bar.

5. An attachment for mitering machines,

comprising a body provided with a face arranged at a given angle forreceiving the ends of printers rules, and a block removably mounted onsaid face, said block being provided with an overhanging shoulderoverhanging part of said face.

6. An attachment for mitering machines, comprising a body having a ruleengaging surface arranged at a given angle, said'body having anaperture, and a filling block adaptedto engage said surface, saidfilling block being provided with a pin adapted to fit into saidaperture.
